---------------------------
Summary: Avoid requestPartitionState from JM but always try
retrigger
Key: FLINK-10319
URL: https://issues.apache.org/jira/browse/FLINK-10319
Project: Flink
Issue Type: Improvement
Components: Distributed Coordination
Affects Versions: 1.7.0
Reporter: 陈梓立
Assignee: 陈梓立
Fix For: 1.7.0
Do not requestPartitionState from JM on partition request fail, which may
generate too many RPC requests and block JM.
We gain little benefit to check what state producer is in, which in the other
hand crash JM by too many RPC requests. Task could always
retriggerPartitionRequest from its InputGate, it would be fail if the producer
has gone and succeed if the producer alive. Anyway, no need to ask for JM for
help.
